Abstract
In a liquid fuel cell including a plurality of series-connected unit cells each including a fuel electrode and an oxidizer electrode disposed opposite to each other with an electrolyte layer being interposed therebetween, a fuel chamber disposed adjacent to the fuel electrode, and an oxidizer chamber disposed adjacent to the oxidizer electrode, and fuel tanks supplying liquid fuel to the fuel chambers, at least two vertically-spaced passages permitting communication of the fuel tanks with all of the fuel chambers are provided so that one of them serves as a passage for liquid fuel while the other serves as a passage for gas produced at the fuel electrodes, the liquid fuel in an amount smaller than the tank volume is charged in each of the fuel tanks to leave a non-charged space, and gas vent ports provided with gas-liquid separating means are disposed midway of the passages and/or on the tank wall portions corresponding to the non-charged spaces defined in the fuel tanks. The liquid fuel cell can satisfactorily generate power at whatever attitude, and gas produced at the fuel electrodes can be vented to the exterior of the cell without leakage of liquid fuel.
